Title: Ship for transporting volatile liquids
IPC: B63B25/08
Filed: 1963-08-20
Abstract: 992,364. Trimming ships carrying liquefied gas. PHILLIPS PETROLEUM CO. Aug. 20, 1963 [Sept. 4, 1962], No. 32867/63. Headings B7A, B7M and B7S. A ship comprises a plurality of horizontally spaced cargo tanks containing a volatile liquid, means for withdrawing vapour from said tanks and compressing, cooling and condensing at least a portion of said vapour into liquid, and means for selectively returning said liquid to said tanks such that when the ship lists in one direction a major portion of the liquid is returned to one of the tanks that is located in the opposite direction, whereby the ship is partially righted. As shown, vapour 13 is withdrawn from tank 8 and passed through line 14, valve 16, line 17, tank 18 and line 19 by compressor 21, which compresses the vapour and forces it through line 22 into indirect heatexchanger condenser 23. Vapour which is left and condensed liquid pass through valve 26 and lines 28 and 27 respectively into chamber 29 of tank 31. The outlet valve 32 of tank 31 is controlled by float 33 and when the liquid rises above a fixed level valve 32 opens and liquid passes through line 34 into liquid distributing tank 36 extending athwartships. The liquid level 37 depends upon the degree of listing of the ship. The port side of the tank 36 communicates via line 38 with tank 11 and the starboard side via line 39 with tank 8. Thus for a port list as shown, the liquid will flow into starboard tank 11. Each tank 8 and 11 has means to spray the returned liquid through a Venturi 72, or 73. During unloading of tanks 8 and 11, the vapour in tank 18 is pumped by compressor 21 through by-pass valve 48 and line 66 into tank 36 and hence via lines 38 and 39 into tanks 8 and 11 where it forces the liquid in said tanks through valves 49 and 51 and lines 68 and 67, and through valve 53 into tank 18 where it is pumped by pump 63 through to the unloading lines. Valve 53 is operated by liquid control level 61. In a modification, the means to return liquid to the distributing tank includes a flow control valve operated by a motor adapted to open said valve responsive to a drop in pressure downstream of said valve below a predetermined value (Fig. 2, not shown). Fig. 2 (not shown) also illustrates the invention with the functions of the distributing tank and tank 18 combined in one tank.

Title: Improvements in polyester urethanes
IPC: C08G18/42
Filed: 1955-11-25
Abstract: A process for preparing an essentially linear rigid, high-softening point, thermoplastic polyester urethane comprises preparing a hydroxy-terminated polyester of a glycol having the formula HO-R-OH where R is an alkylene radical containing from 4 to 10 carbon atoms with an aliphatic dicarboxylic acid or an anhydride thereof, said polyester having a molecular weight from 400 to 1500 and being prepared by reacting together by heating the glycol and the acid in a molar ratio of glycol to acid greater than one and continuing to heat the reactants at reduced pressure until a polyester of the desired molecular weight is obtained, the polyester then contacted with water, extracting therefrom low molecular weight materials, recovering the polyester residue and then reacting the recovered polyester with an organic diisocyanate.  Preferably the polyester has a molecular weight of 700 to 1,000 and an acid number less than 1. Specified reactants for its preparation are adipic, succinic, maleic, fumaric, methyl succinic, di-, tri and tetramethyl succinic, pimelic, glutaric, suberic, azelaic and sebacic acids and tetra, penta, hexa, hepta and octamethylene glycols and 2-methyl butanediol-1,4.  The extraction is preferably effected at a temperature above 50 DEG  C. and with the polyester in a fluid state, and the treated polyester is then dried.  The molar proportion of diisocyanate is preferably 1 or 1.1 mols. of diisocyanate to 1 mol. of polyester, though it may be between 0.9 to 1.5 mols.  Suitable polyisocyanates are hexamethylene, tetramethylene, 1,5-naphthylene, di- or triphenylmethane-p,p1, m-toluylene, phenylene and 4,41-benzidine diisocyanates.  The products can be repeatedly softened by heating.  In an example a polytetramethylene adipate of hydroxyl number 130 and molecular weight 849 (prepared by reacting at 200 DEG  C., 3 mols. of tetramethylene glycol with 1 mol. of adipic acid at reduced pressure at the end of the reaction) is extracted by swirling with water at 70 DEG  to 80 DEG  C.  The dried product (of hydroxyl number 114 and molecular weight 966) is reacted at 90 DEG -110 DEG  C. in vacuo with an equimolecular amount of p-phenylene diisocyanate and then at 140 DEG  C. in an oven.  The product has a softening point of 266 DEG  C. compared with a softening point of 85 DEG  C. of a product prepared from the unextracted polyester.  The products are suitable adhesives for metals, ceramics, rigid plastics and cellulose products and may be applied (in solution in tetramethyl urea or dimethyl formamide) to bonding a plurality of layers of such materials.  Specification 781,469 is referred to.

Each secondary winding is connected to a respective energizing winding 23, 24 of a differential magnetic device 21 having an armature 22b which moves in response to unbalanced energization of the windings 23, 24 to open contacts 40 controlling the operating coil 33 of a contactor 31. Under normal conditions, current induced in the secondary windings 14, 15 by the winding 13 energizes the windings 23, 24 equally so that the armature 22b does not rock about its support 26, but an armature 22g is attracted to close contacts 42 so completing the circuit for the coil 33. Should unbalance occur in the supply conductors, the current induced in the secondary windings 14, 15 differ so that the currents in the windings 23, 24 differ and the armature 22b rocks to open the contacts 40. Should the supply voltage fail or should an open circuit occur in the windings 13 ... 15 or 23, 24 the armature 22g is released to open the contacts 42 so providing a checking facility. In addition an under and overvoltage relay connected across the supply conductors may have its contacts in series with the coil 33, Figs. 3, 4 (not shown). The two magnetic circuits may be provided by separate cores, Fig. 2 (not shown). Various modifications of the device 21 are specified. Overcurrent protection may be provided by fuses in the supply circuit.
